I will admit that those three are from literally dozens and dozens of shots that weren't anywhere near as good. But that's the beauty of having a digital camera. You can just keep clicking and clicking and trying different lenses and setups until you get something that your happy with. If I remember correctly the middle on I had two 2X barlow a 20mm lense and the 3X optical zoom going. The colour looked terrible (achromatic barlow) so I just greyscaled it
(You can cheat a lot on the moon.) Its one of my favourite moon shots.
